Specify the last subject in the list of subjects you used to create the average as the source subject. Specify the average subject itself as the target subject, specify lh.avg_curv as the source input and lh.curv as the output (in the average subject surf dir). You can also look at the --help

Thanks, Doug,
I never used mri_surf2surf, the latest version I downloaded.
Would you be more specific on how to convert avg_thickness to the average subject?
(I tried mri_surf2surf --srcsubject SUBJECT --tfmt avg_thickness, but it's asking a whole lot more variables...)

Does it work if you don't use projfrac? We have a bug in the make_average_subject code that causes the average thickness (lh.avg_thickness) to be painted on the last subject in the list instead of the averaage subject. One work-around until we get this fixed is to convert the avg_thickness to the average subject with mri_surf2surf. This will require a new version of surf2surf, which you can get from:
ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_surf2surf
Run it with --tfmt curv

Dear all,
I've been waiting for an answer to the following question.
I am trying to overlay group-averaged data (FSL) on an averaged anatomical brain (Freesurfer). I did the following,
mri_vol2surf --src AVG.gfeat/cope1.feat/thresh_zstat1.img --src_type
analyze
--srcreg register.dat --hemi lh --projfrac 0.5 --out AVG.gfeat/cope1.feat/thresh_zstat1-lh.w --out_type paint
and got the following error message,
MRISreadCurvature: could not open /home/nam/AVERAGE/average/surf/lh.thickness No such file or directory
In the surf directory, I DID find "lh.avg_thickness". I renamed "lh.avg_thickness" "lh.thickness", but it didn't work. Would someone please let me know how to remedy this?
Nam.
